Description

Compared with other compounds in its class, the molecular weight of 209.05 g/mol gives 4,5-Dichlorothiophene-2,3-dicarbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5-Dichlorothiophene-2,3-dicarbaldehyde (CAS 89465-82-7), molecular formula C6H2Cl2O2S and molecular weight 209.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,5-Dichlorothiophene-2,3-dicarbaldehyde (C6H2Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4,5-Dichlorothiophene-2,3-dicarbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
